hey everyone i have a JD that is about 5 inches. and for some reason he is starting to act crazy. Yesterday morning when the lights came on he start running around in the tank and then he jumped out and landed on the floor. Then last night a few minutes after i turned of the lights he went crazy again and then jumped out and landed on the glass. SO i was able to save him both times but he is hurt pretty bad from hitting thing. SO I closed up everything to make sure he can jump out again. And this morning i hear him banging the stuff i used closed up the holes with trying to get out. can anyone tell me what i can do to stop this before he kills himself
